Say goodbye to touching door handles and metal keys

Narrowband Smartlock is easy to install - you don’t have to replace your existing door lock (or your keys), and you don’t need a professional. All you need is a screwdriver.

Easy install on inside of your door

Connect to the global IoT network

With tiny modems and SIM cards inside our smartlocks connect to the internet with NB-IoT communications technology (part of the 5G standards). Also included is a 500MB pre-paid data plan which typically lasts around 3 years (assuming 5 lock activations a day)

When a delivery driver arrives at your house with your package, they can scan the smartlock QR code on your door, and the package barcode to trigger an unlock command. Your door unlocks just once, and your delivery driver slides your package iside without setting a foot inside.  

Safely receive parcels inside

Always alert like an alarm

Narrowband Smartlock senses any door movement (e.g vibrations) when it’s locked. You’ll receive a notification anywhere in the world if anyone tampers with your door, or tries to force your door open.
